• Repetition
• There are many competing theories of memory

Competing Theories of Memory

• The Total Time Model
• The longer you spend thinking about something,
  the better you will remember it
• Explains classic repetition findings
• The Levels of Processing Model
• a.k.a. The Depth of Processing Model
• Structural, Phonetic and Semantic levels
• The deeper you think about something the better
  you will remember it

4
The Total Time Model

• Time is directly related to memory
• More time more memory

5
Levels of Processing Model

• The more deeply you process something, the better
  you will remember it

Todays Experiment

• Design
• IV depth of processing
• structural gt uppercase letters
• phonetic gt rhymes with X
• semantic gt category
• DV1 RT
• DV2 of correctly recalled words

Discussion

• Both models apply!
• Semantic level
• ? most accurate
• ? slowest reaction time
• Primacy/Recency effects
• every day life example studying for exams
